Solving Algebraic Equations

To solve algebraic equations, we must combine like terms and perform inverse operations on both sides of the equal sign to isolate the variable.

• The inverse operation of addition is subtraction, and vice versa.
• The inverse operation of multiplication is division, and vice versa.

Inverse operations help us cancel values out.

Solving the Question

`- 4 a - 2 a = - 18`

⇒ First, combine like terms:

`- 6a = - 18`

⇒ a is being multiplied by -6. To isolate a, divide both sides by -6:

`(- 6a)/(-6) = (- 18)/(-6)\\\\a=3`

Answer

a = 3
